Quick Summary
A One Time Registration (OTR) portal is a recruitment body's own website where you build a candidate profile once and reuse it for every future notification from that same body — this page explains the concept in plain language.
What Is an OTR Portal
An OTR portal is the official website of a recruitment commission — a state PSC, staff selection board, or a central body like SSC or UPSC — where candidates create a single profile containing their personal, educational and category details. Once created, that profile is reused for every future notification published by that same commission, so you don't fill the same form repeatedly.
Why It Exists
Before OTR systems, candidates had to re-enter identical personal and educational information for every single exam application, which was repetitive and error-prone. Recruitment bodies across India have moved to OTR to cut this duplication, speed up the application process, and reduce data-entry mistakes on official records.
There is no single national OTR portal. Each recruitment body — SSC, UPSC, and every state PSC or staff selection commission — runs its own separate system, so a registration on one does not carry over to another.
How to Use One
- Identify the correct official portal for the specific commission you're applying to.
- Register with your mobile number and email, and verify via OTP.
- Fill in personal, educational and category details accurately.
- Upload your photograph and signature in the specified format.
- Submit to receive your unique OTR/registration number — save it permanently.
- Use that same number to apply to any future notification from that commission.

Frequently Asked Questions
No. Every recruitment commission — central or state — runs its own separate One Time Registration portal. There is no single unified system.
Creating your OTR profile itself is typically free across most commissions. Exam-specific application fees, where applicable, are charged separately.
Most portals allow limited correction of contact details, photo or signature before a notification's application window closes. Core details like date of birth often need a formal correction request.
Conclusion
Once you understand that every commission runs its own OTR portal, the next step is simple — find your specific state or central body's page on this site and complete registration there directly.
